Answer:
8800πcm^2 or
(8800)(3.14)cm^2
276.32m^2
Step-by-step explanation:
volume of cylinder is given by πr^2h
and according to question the rectangular sheet was folded along width . hence it will become a cylinder having radius 10 cm and height of 88cm
then by putting the value of 'r' and 'h' you will get the answer .
i.e 8800πcm^2
Answer:
h=20cm
2πr=88cm
2× 22/ 7×r=88cm⇒r=14cm
URl=πr2h=22/ 7 ×14×14×20
=22×2×280
=22×560
=12320cm3
